CD Projekt Red's CEO Adam Kicinski has told fans of The Witcher that the development studio won't be abandoning the series – explaining that not making a follow-up to this year's The Witcher 3: Wild Hunt "wouldn't be fair to fans".
During an interview with Polish TV Station TVN24 BiS (catchy) about the game's success, Kicinski said in response to a question about a potential sequel: "It's too early to talk about it, but it's not like we're forgetting about this brand - that's understandable. It wouldn't be fair towards the fans. We work within this universe for over a dozen years now and I don't think it's going to be the end of it." (Via PCGamesN)
Whatever plans they have, we won't see another Witcher game for a few years at least. CD Projekt's next game is Cyberpunk 2077, a sci-fi role playing game that's been in the oven for quite a while already.
While The Witcher 3 was well publicised as the end of protagonist Geralt's story, it was never likely to be the end of the series. The game's success following its release in May – it sold 6 million units in its first six weeks on sale – only made this more likely.
With Wild Hunt, CD Projekt Red took the series fully open world for the first time – expanding on the fiction based on the fantasy novels of Andrzej Sapkowski. There are numerous characters who could star and opportunities to explore in The Witcher's world.
